Cerebral infarction has its own law of development and evolution. After cerebral infarction, there will be permanent residual lesions on imaging, and some symptoms of neurological deficits may remain due to the non-regenerative nature of nerve cells, which we call sequelae, but in general, it is still preventable and treatable. In the acute stage of cerebral infarction, the treatment of revascularization should be carried out as early as possible to improve the blood supply in the relatively ischemic area around the infarction by means of restoring blood flow, so as to achieve the purpose of saving brain cells. In addition, with the advancement and maturity of technology, endovascular treatment techniques have been gradually improved, and the occluded blood vessels can be recanalized within a short period of time to preserve the neurological function to the greatest extent and achieve very good results. Cerebral infarction is actually only a disease process, not the end of the disease, and it is necessary to make full use of modern treatment technology to clarify the causes of cerebral infarction and carry out targeted preventive treatment for the causes in order to prevent recurrence of cerebral infarction, which is also an important aspect to achieve the purpose of cure. For patients with sequelae, along with drug treatment, rehabilitation treatment should be carried out to restore the patient’s motor and self-care ability, and pay attention to the patient’s psychological state to promote the patient’s return to the family and society, so as to achieve the purpose of curing cerebral infarction functionally. In conclusion, cerebral infarction is a complex process, and most patients with mild cases can reach the clinical cure standard through active treatment and prevention. However, they should adhere to the corresponding medications as prescribed by the doctor, control the risk factors and maintain a good state of mind to prevent recurrence of cerebral infarction.
